I'm currently using QuantLib to perform financial calculations in my application, but I'm having trouble finding a DayCount convention that supports the India financial year calendar (April 1 to March 31).
I've tried using the Actual/365 (Fixed) convention, but this assumes a calendar year of January 1 to December 31. I've also looked into the Actual/Actual (ISDA) convention, but I'm not sure if this is appropriate for India financial year calculations.
Does anyone know if QuantLib has a DayCount convention that supports India financial year calculations? If not, what would be the best approach to implement this in my application?
Thanks in advance for any help or guidance you can provide!
